             function disableBack() { window.history.forward() }
             window.onload = disableBack();
             window.onpageshow = function (evt) { if (evt.persisted) disableBack() }

推荐答案

（document）.ready（function（）{
function disableBack（）{window.history.forward（）}
window.onload = disableBack（）;
window.onpageshow = function（evt）{if（evt.persisted）disableBack（）}
}）; **

(document).ready(function () { function disableBack() { window.history.forward() } window.onload = disableBack(); window.onpageshow = function (evt) { if (evt.persisted) disableBack() } });**

您无法禁用浏览器按钮，但可以阻止它使用。



以下代码可以帮到你 -

You cannot disable the Browser button, however you can prevent it to use.

Following code may help you -

<script type="text/javascript" >
   function preventBack(){window.history.forward();}
    setTimeout("preventBack()", 0);
    window.onunload=function(){null};
</script>
